West Control Solutions KS 94 - Manual (Page 6)

8.3 Connecting input INP6
2
For position feedback with 3-point stepping controller
(other selections possible in configuration level
C.180).
8.4 Connecting input INP5
3
Input for process value x2 or external set-point or external
x2 set-point offset (configuration level
C.180). With voltage signals,
A6 must be connected to the reference potential at A9.
8.5 Connecting the power supply
5
Depending on the version, the instrument is supplied with: 90...250 V AC or 24 V UC. The
24 V UC version is for 19,2...30 V DC or 20,4...26,4 V AC. The indicated values are the limits. The
protective earth must be connected to terminal P3.
8.6 Connecting the outputs OUT2/4/5
6
Relay outputs, corresponding to the controller output Y2 or the alarms LIM1 / LIM2 (other selections
possible in configuration level
rfrom page 26).
8.7 Connecting output OUT1
7
Depending on the version, OUT1 is a relay, logic or continuous output corresponding to the
controller output Y1 (other selections in configuration level). With logic and continuous outputs, P13
must be connected to the earth terminal. The logic signal is 0 / >20 mA (load
ß600 [) or 0 / >12 V
(load
?600 [).
8.8 Digital inputs and outputs (di / do)
4890"§$
The inputs operate as current sink (IEC 1131 type1), logic „0" = -3...5 V, logic “1" = 15...30 V.
The outputs operate as „grounded load“. They are short circuit protected and contain recovery diodes.
The digital input and supply voltage (24V) must be connected on each circuit board.

di1 / di2 control various actions (set in configuration level
C.190/ C.191 and
parameter
Blck1 / Blck2)

di3 is used for changeover Local mode(0)
i Remote mode(1).
0
di4...di7 and do1...do4 are correlated to the programmer as follows:
di4 Program STOP (0)
i RUN (1)
do1 Status fo control output 1
di5 Program normal (0)
i RESET (1)
do2 Status fo control output 2
di6 Program number (LSB) do3 Status fo control output 3
di7 Program number (MSB) do4 Status fo control output 4
di6 0 1 0/1 di8 0 1 0 1
di7 0 0 1 di9 0 0 1 1

di8 / di9 is used for selecting the parameter set (bei C.700 = xx.x.
3, di9 = MSB).
